Two arc-shaped ditches, one running thirteen metres and the other ten, came to light under archaeologically monitored conditions, their curving lines suggesting the partial outline of an enclosure whose full extent and original purpose remain open questions.

What made the discovery particularly striking was what the ditches contained. Both held large quantities of iron slag and burnt bone, a combination pointing to sustained activity rather than casual occupation. Iron slag is the residue of smithing, the waste material left when iron ore is worked at high temperature, and its presence here in volume suggests metalworking took place at or near this site. The burnt bone adds a further layer of ambiguity: it could indicate feasting, ritual disposal, or simply the general debris of a working settlement. To the east of the ditches, excavators also identified the possible remains of a fulacht fia, a type of prehistoric cooking site typically recognised by its characteristic horseshoe-shaped mound of burnt and shattered stone, formed through repeated cycles of heating stones and plunging them into water-filled troughs. The association of a fulacht fia with metalworking residues and enclosure features in the same landscape is a pattern that has emerged at other Irish sites and continues to prompt debate about how these different activities related to one another. The excavation was carried out under licence in 2003, with the results published by Molloy in 2006.
